The impact of microbial ecology on operation of biosolids treatment trains

This project has four specific objectives: (1) To identify ways to prevent or reduce the incidence of foaming during anaerobic digestion of sewage sludge; (2) to identify the core microbiome associated with efficient digestor performance during stabilisation of sewage sludge; (3) to assess how changes in the reactor environment affect contaminant transformations; (4) to assess the impacts of biosolid post-treatments on the metabolic capacity of the microbial community, pathogen-survival, contaminant-transformations and ecotoxicology of final products.

PhD Thesis underway by Timothy Micallef.
